  22. def withCloseable [C, T] (closeable: C)(block: (C) ⇒ T)(implicit arg0: (C) ⇒ Closeable): T

    Ensure that a closeable object is closed.

    Ensure that a closeable object is closed. Note that this function uses a Scala structural type, rather than a java.io.Closeable, because there are classes and interfaces (e.g., java.sql.ResultSet) that have close() methods that do not extend or implement java.io.Closeable.

    Sample use:

    withCloseable(new java.io.FileInputStream("/path/to/file"))
{
    in => ...
}

    The closeable object is not passed into the block, because its type is useless to the block.

    closeable

    the object that implements Closeable

    block

    the code block to execute with the Closeable

    returns

    whatever the block returns

  1. def useThenClose [T] (closeable: Closeable)(block: ⇒ T): T
